Question
Title: Understanding the Normal Distribution of IQ Scores --- **Find the Area of the Shaded Region** The graph on the right illustrates the distribution of IQ scores among adults. These scores are normally distributed with: - Mean (μ): 100 - Standard Deviation (σ): 15 **Graph Explanation:** The bell curve represents the normal distribution of IQ scores. The shaded area between the scores of 104 and 122 highlights the segment of the population whose IQs fall within this range. **Calculating the Shaded Area** The task is to find the area of the shaded region, which represents the probability of an adult having an IQ score between 104 and 122. *Note: Round your answer to four decimal places as needed.* --- This exercise demonstrates how the properties of a normal distribution can be used to calculate probabilities for specific ranges of data.

**Problem Statement** Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15. *Links for reference:* - [Click to view page 1 of the table.](#) - [Click to view page 2 of the table.](#) **Graph Explanation** The graph presented is a bell curve (normal distribution) illustrating IQ scores. The curve is centered around the mean, which is 100. The area under the curve represents the distribution of IQ scores across the population of adults. **Shaded Region** A shaded region is shown under the curve to the left of the value 70. This area represents the proportion of the population with IQ scores lower than 70. **Calculation Requirement** The area of the shaded region is required to be calculated and should be rounded to four decimal places as needed. **Instructions** Enter the area of the shaded region in the provided box.
